You can easily use a different TURN server for each client. Just change this line: https://github.com/jech/galene/blob/master/rtpconn/webclient.go#L1189 However, given that most clients don't go through a TURN server but connect directly to Galene, I fail to see how that would improve anonymity. -- Juliusz
